Digital twin 3D wind farm, onshore wind power of smart wind power

foreword

During the "14th Five-Year Plan" period, in the fields of digital upgrading and green transformation of traditional industries, green and low-carbon urbanization and modern city construction, green and low-carbon consumption, and renewable energy or power system construction, the total investment can reach nearly 45 trillion, an average of about 8.9 trillion per year, accounting for about 16% of the total investment in the whole society in 2021, which will be a considerable investment growth momentum.

After the "dual carbon" goal was put forward, in order to improve energy efficiency and reduce carbon emissions, many industries have carried out electric energy substitution. In the first quarter of 2022, my country's newly installed renewable energy capacity reached 25.41 million kilowatts, accounting for 80% of the country's newly installed power generation capacity. Among them, hydropower added 3.43 million kilowatts, wind power added 7.9 million kilowatts, photovoltaic power generation added 13.21 million kilowatts, and biomass power generation added 870,000 kilowatts. As of the end of March 2022, my country's installed renewable energy power generation capacity reached 1.088 billion kilowatts.

Show results

As the proportion of new energy installed capacity continues to increase, the demand for 3D visualization of new energy wind power generation is also increasing. In order to centralize the management and control of wind power generation, improve the digital and intelligent level of user enterprises, and realize data visualization management, it has become a new mainstream trend to create a set of three-dimensional visualization centralized management modules suitable for new energy.

The front-end visualization engine HT for Web independently developed by Hightopo is used to realize the interactive Web wind power generation digital twin 3D scene. It can switch between day, night, sunny, overcast, and rain according to the time and weather interface, presenting a space-time state consistent with the real world.

The digital twin 3D visualization system of Tupu software can realize roaming inspection and remote monitoring of wind turbines, booster stations and power distribution rooms. There are four buttons for roaming animation, pause animation, stop animation, and initial perspective in the scene. You can perform first-person perspective roaming or drone perspective roaming for different scenes.

System analysis

bird's eye view

The first-person perspective roaming can bring the peculiar feeling of "I am at the center of the world, and all things take me as the origin", simulating the inspection process in the wind farm, bringing an immersive experience. For sites that may be dangerous, the roaming function provided by Tupu software can be used to conduct outdoor and indoor inspection and roaming of wind farms. At the same time, roaming from the booster station to the air from the perspective of the drone can intuitively show the grandeur of the wind farm and bring a unique and shocking look and feel.

Production monitoring

Due to the unstable air volume of wind turbines, and the ability to support the operation of the power system is not as good as other power generation fields, the monitoring data of wind power base facilities needs to be more timely. The key production data of the wind farm are concentrated on the left and right sides of the interface, providing managers with intuitive data display and timely control.

The 3D visualization technology of Tupu software adopts B/S structure, and the page adapts to various resolutions. Users can access the 3D visualization system anytime and anywhere through PC, PAD or smart phone, as long as they open the browser to realize remote monitoring and control.

Using the visualization scene of Tupu software, the real-time operating parameters of smart devices are connected to the 2D panels on both sides, and complex and abstract data such as project overview, real-time indicators, unit status, environmental parameters, power generation statistics, energy saving and emission reduction are displayed in rich Charts, graphics and design elements are displayed for centralized control. Through the fusion analysis of historical data, managers can realize the optimal allocation of resources and build a smart wind power management system.

Environmental parameters

Changes in wind speed and wind direction have a great impact on the power generation of large wind turbines. The environmental monitoring system can be connected to the visualization scene of the Tupu software to complete the real-time monitoring of visibility, precipitation, wind speed and temperature. Take precautions before it arrives.

Power Generation Statistics

Power generation is the data most concerned by managers of the production monitoring module. The panel displays the power generation of the day, the current month, and the cumulative power generation; the daily power generation ranking of all wind turbines is displayed in the form of a bar chart.

Energy conservation

Through the visualization system of Tupu software, the emission data of nitrogen oxides in wind power bases can be remotely monitored and counted, and the optimal solution of energy saving and emission reduction can be achieved by following the rules.

Popular science tips:

The United Nations Economic Commission for Europe's report on "Lifecycle Power Generation Options" pointed out that in the full life cycle of a power station, wind power generation without carbon capture technology will emit 10 grams of carbon dioxide per kilowatt-hour.

Number of unit states

Using the various chart forms of Tupu software, it can display the number of wind turbines with normal power generation, diseased power generation, standby, self-limited power, planned shutdown, and communication interruption, so as to facilitate the real-time acquisition of the running status of the fans in the whole field.

Booster station monitoring

Through on-site framing photos, satellite images, CAD maps and other materials, Hightopo can quickly restore the real wind power base online, and realize digital twins through data access. The streamer effect is used to simulate the process of the currents of different wind turbine collector lines converging to the booster station, and the wind power generation process can be displayed more intuitively, bringing a better immersive experience, viewing experience, and interactive experience.

A wind farm booster station refers to a facility that boosts the output voltage of a wind turbine to a higher voltage and sends it out. Since most of the wind turbines are asynchronous generators, the wind farm will absorb reactive power while generating active power, and most wind turbines cannot perform continuous and effective active and reactive power regulation. power and voltage stability, or increase the network loss of the power grid.

In order to solve the problem of voltage stability of the sending system caused by the grid-connected operation of large-scale wind farms, the reactive power compensation method in the wind farm's collective booster station generally adopts the combined operation of static var generator (SVG) and parallel capacitor bank.

Click on the 3D model of the booster station to jump to the perspective of the booster station, and display the main observation data in the station, such as environmental information, load statistics, wind power prediction, fire inspection information, inspection vehicle information, etc.

Realize value

The ability of new energy to provide long-term stable power guarantee is poor, and due to the rolling update of meteorological data, the power forecast of new energy still deviates from the actual results. The large-scale access of new energy has exhausted the existing conventional power supply and pump-storage regulation capacity, and the balance mode of "source-to-load" is unsustainable. The system's balance and regulation capacity needs to be improved urgently, and it is necessary to speed up the construction of "source-grid-load-storage" interaction new power system.

The "source-network-load-storage integration and multi-energy complementary platform" takes the data middle platform as the system, adopts the micro-service architecture, and uses the Internet of Things, big data, intelligent AI and other technologies to realize various types of power supply side, load side and energy storage side. Data access and data processing of controllable resources, realize transparent perception of data resources, feature modeling, performance evaluation and modeling applications, and provide resource information management, evaluation services, production services, resource control capabilities and transactions for power systems Capability assessment and adjustable load application services consolidate the data foundation and provide accurate assessment methods.
